Reassembly
6. Repeat this procedure for the other connecting
rod and piston assembly.
Install Camshaft
1. Liberally apply camshaft lubricant (see Section 2)
to each of the cam lobes. Lubricate the camshaft
bearing surfaces of the crankcase and the
camshaft with engine oil. See Figure 10-21.
Determining Camshaft End Play
1. Place a new closure plate gasket into position on
the crankcase.
2. Position the camshaft end play checking tool
over the camshaft. Use a feeler gauge to check the
end play between the camshaft and end play
checking tool. Camshaft endplay should be
between
0.3/1.3 mm (0.011/0.051 in.)
. See Figure
10-23.
Figure 10-21. Apply Camshaft Lubricant to Cam
Lobes.
2. Position the timing mark of the crankshaft gear
at the 12 o’clock position.
3. Slide the camshaft into the bearing surface of the
crankcase, positioning the timing mark of the
camshaft gear at the 6 o’clock position. Make sure
that the camshaft gear and crankshaft gear mesh,
with both timing marks aligned. See Figure
10-22.
Figure 10-23. Checking Camshaft End Play.
3. No shim is typically used from the factory.
However, if the camshaft end play is not within
the specified range, remove the checking tool and
shim as necessary.
Several color coded shims are available:
White:
0.69215/0.73025 mm (0.02725/0.02875 in.)
Blue:
0.74295/0.78105 mm (0.02925/0.03075 in.)
Red:
0.79375/0.83185 mm (0.03125/0.03275 in.)
Yellow:
0.84455/0.88265 mm (0.03325/0.03475 in.)
Green:
0.89535/0.99345 mm (0.03525/0.03675 in.)
Gray:
0.94615/0.98425 mm (0.03725/0.03875 in.)
Black:
0.99695/1.03505 mm (0.03925/0.04075 in.)
4. Reinstall the end play checking tool and recheck
the end play.
